SPECIFICATION forming part of Letters Patent No. 769,229, dated September 6, 1904,

' [ipplicati-:n filed November '7, 1906. Serial No. 35.720.v (No model.)

To IJ/Z 1077/0111, it www] concern:

Be it known that we, WILLIAMB. PAGE and p 'ARCHIBALD E. HOPKINS. citizens of the United States, and residents of Dixon, in the county of lLee and State of Illinois, .have invented certain new and useful Improvements in Caramel Cut- -ting and Wrapping Machines; and we do hereby declare that thefollowing is a full, clear, and

as in the former instance the candy is introf troduced to the said mechanism in strips of indefinite length and v'each severed portionas, for instance, a caramel-is at the conclusion of the operation delivered at the required place, to be there subsequently taken up and inclosed in a wrapper by other instrumentalities, which, though many of them are shown 50 in the present drawings, constitute no part of our invention to be patented hereby.

The invention consists in the matters here inafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a plan view of a complete caramel cutting and wrapping machine embodying our invention. Fig.V 2 is a front elevation o f the same. Fig. 3 is a sectIon takenon line 5 5 of Fig. 1. Fig. 4C Is a section taken on line lO 10 of Fig. l. Fig.;'5 is a section taken on linell l1 of Fig. 1.

Fig. 7 is a Fig.v

10 is a section taken on line 14 14 of Fig. 6. Fig. Vl1 is asection taken on line 15 l5 of 50 Fig. 9. Fig. 12 is an-enlarged detail in perspective of the end of the feed-chute and the knives.` Fig. 13 is a detail of apart acting to hold the caramel in positionduring the retraction of the knife. -Y 5 5 In Said drawings, referring first to the general construction of the machine, (later to the specific mechanisrrn) A is4 a table or bed-plate, from which are supporteds'tandards B, B', and B2, rigidly secured invalinement on the table A. On the upper ends of these standards are bearings in which is journaled the main shaft C of the machine. On one end of this shaft are a suitable drive-pulley C and a loose pulley C2, as seen in Figs. 1 and 3. Rig- 65 ridly secured on the Shaft C are the cam-disks D and D2, which vare provided with camgrooves on their faces or edges designed for operating the various mechanisms hereinafter described. Extending fromthe standard B tothe standard B is a rod or non-rotative shaft C3, on which are Secured various levers, which are operated by the cams just mentioned. Mounted also on the shaft C, Fig. 3,

is a wheel or disk having. a series of pockets in which the articles to be wrapped (in this case caramels) are carried d uring the wrapping operation. In axial alinement with the shaft C and rigidly Secured on the bed-plate A is the fixed cam-plate E', having in its face adja- 8O cent to the caramel-carrying wheel a series of cam-grooves adapted to operate vthe various mechanisms carried by the caramel-carrying wheel E as the same revolves. The Various cam-plates with the exception of the plate E, 8'5 whic his secured on the bed-plate, revolve continuously and uniformly, While -the caramelcarrying wheel E is given an intermittent motion by mechanisms unnecessary tol` be de- Iscribed in our present application.

The standards B3 Bf, respectively, are rigidly secured on the bed-plate A adjacent to thefront edge and at each end of thesame. Supported at its ends in suitable slots on the top of the standards B3 and BA1 is a slide-bar 95 F, adapted to reciprocate parallel with the `arms GG is provided at its extremity with shaft C and having connected therewith the l candy-cutting knives. Part of said slide-bar constitutes a movable floor-section for the feed-chute, to be described. Said slide-bar consists of a narrow plate rectilinear in crosssection and bent upwardly and offset intermediate of its ends, as shown in Fig. 9. Above said slide-bar and parallel therewith is a table F, rigidly secured on the top of the standard B3, with its top surface in alinement with the upper surface of the front end of the slidebar, part of said table constituting' a stationary floor-section for said feed-chute. The rearwardly-disposed edge of that portion of the slide-bar*constituting the movable floorsection above described is beveled to make an obtuse angle with said floor, and the oppositely-disposed forwardly-presented edge of said table is complementally beveled, whereby the two Hoor-sections are closely jointed when the slide-bar is in retracted position, as shown in said Fig. 9, and the slide-bar moves backward with less friction against the superdisposed candy. On each side of the table F are rigidly secured the upwardly-projecting longitudinal stripsff, which constitute ways between which the candy or material to be operated upon moves.

F2 indicates an arm pivot-ed on a stud projecting horizontally from the standard B3. Said arm projects upwardly and is provided at its upper end with a roller which engages in a cam-groove in the periphery of the camdisk D2, as shown in Figs. l, 2, and 5. Adjustably secured by means of bolts fm fu to the arm F2 is a bar F3, which extends upwardly between the feed-chute and the disk D2 and has pivotally secured near the top of the same the bent arm Ff, which extends downwardly and forwardly beneath and transversely of the feed-chute and has pivotally secured thereon the slide-bar F and forming a part of the bottom of said feed-chute and the reciprocating bars G and G,mo1e fully shown in Figs. l, 2, 7, and 8. Said bars extend longitudinally of and upwardly along the sidesf of the feed-chute. The sides ff of said feed-.chute terminate short distance from the caramel-carrying wheel E and, as shown, are each provided with two horizontal slots g, one located above the other. Secured on opposite sides of the slide-bar F in position to slide within the ends of the strips ff, which are bent outwardly for that purpose, are the upwardly-projecting plates f f'. Said plates are' slotted to correspond with the ends of the plates ff. Each of said a head Gr2 g3, respectively. The head Gti-secured on the arm Gr, is double and provided with two vertical parallel knives or cutters g g', respectively, adjusted a distance apart equal to the desiredlength of the caramel. The head g3 is provided with but one knife or cutter. g2, .which is located opposite the knife f/ and is adapted to coact therewith. Said knives are directed inwardly, and the knives ,f/ and .r/i coact to give a first cut to the caramel, while the knife y is suiiiciently long to insure an entire cut through any medial portion of the strip left unsevered between the opposite edges of the knives f/ and g, thus insuring a complete severance of the caramel from the strip without contacting the knife-edges against a block or other bearing. A plate f2, forming, in effect, a continuation of the outer side wall f of the feed-chute, is secured on the outer side of the slide-bar and fits between the knives .r/ y', and a similar plate f" is secured opposite thereto. A sufficient space is left between the ends of the plates f and f2 and the inner platef and the plate f to permit the passage of the knives between the same in cutting the caramel. Said plates are designed to prevent the cut caramel from falling or being' forced laterally out of the chute before retraction of the knives. Said slide-bar F, the bars Gr and G, with the knives secured therein, are given movement longitudinal of the table F by means of the arm F, heretofore described, the bent arm F'1 being so formed for the purpose of carrying the connection with the bar Fi to a point suiiiciently high to permit adjusting the stroke to a desired length of cut and to compensate for wear of parts, and it is obvious that the greater the distance between the pivotal connection of the part Fj and the pivot of the bearing on the standard B3 the greater will be the length of the stroke, and the reverse. It will thus be seen that the movement of the slide-bar and the knives longitudinally of the feed-chute maybe regulated as desired. Means for operating the said arms and the cutting-knives thereon, as described, are as follows: AParallel with the shaft C and on the opposite side of the same from the shaft C is a non-rotative shaft C", also having its bearings on the standards .l and B'. The cam-disk D is provided on its face remote from the carrying-wheel E with two cam-grooves l d', respectively. On the shaft C:i is journaled an arm H, which extends upwardly and is provided near its upper end with a roller which engages the camgroove ZC A connecting-rod /t is pivoted at its outer end on the arm G', and, as shown, passes loosely through said arm H and is provided on its end which protrudes at the rear of said arm with a spring, one end of which abuts against the arm and the other end of which abuts against a nut or other suitable device on the outer end of the connecting-rod. Said connecting-rod is provided in front of said arm with a collar /f/T, having a transverse ridge across its face and adapted to engage in a complemental groove in the face of a collar /L which engages against the arm, thereby forming a universal joint with the arm H. T he inner side of said caln-disk D has IOO .lIO

but a sinole cam-groove cl2, in which is en-i gaged a roller pivoted near the upperfend of an arm H', which is also pivoted on the shaft O, and a connecting-rod 7L extends beneath the feed-chute and arm G and pivotally engages the arm G, as indicated in Figs. l and 4; Said connecting-rod /Lis secured on thev arm H in a manner similar to that in which the connecting-rod 7L is secured on the arm `H except that the universal joint is provided on the rear side of said arm and the spring is on the front side thereof. Owing to the peculiar character of the material to be wrapped it is desirable that the cutting be done slowly.

Said cam-grooves are `ofsuch-conformation' and said cam-disks are so adjusted with re-v spect to each otherthat when the slide-bar F. and the arms G G are retracted longitudinally'of the feed-chute the knives secured to the heads thereof are out of engagement with the candy strip in said chute. At said rearward limit said arms are Vreciprocated slowly .knivesin case the candy should be severed before the forward limit of the movement is reached the heads G2 g3 are each provided laterally with pins g4 g, rigidly secured `thereon in` position to project. through longitudi- -nal slots ggg? -in the ends of the side pieces ff and plates f f' and engage the candy strip from opposite sides and behind the knives. Obviously it is important to hold the candy strip in position during the retraction of the knife longitudinally of the chute.

` Forthis purpose we have provided an arm G5, secured on the inner wall f of the candy-l chute by means of .a hingeor other suitable \jointand having at its forward end a pin di- -rected laterally of ,said arm and adapted to project through an aperture in saidv side wall of the chute and engage` the candy when the knives reach their forward position. pin acts .to hold the candywhile the knives are retracted longitudinally preparatory to another. cut. Said arm G5 is operated from the arm H or that which operatesthe arm G. vFor this purpose a connecting-rod if extends `from near. thev top of said arm H and is pivoted to thei free end of the arm G5. Obviously said arms G and G5. being on opposite sides of the candy-chute and both operated by the movement of-the arm H it .follows that when the arm Gis thrown back and the; yknives thereon out of engagement with the,

to be made .relatively thin.

Said

vwithin the chute.

"candy strip the arm G5 is forced inwardly runtil the pin on the outer` endfof the same is projected through the wall f and forced intothe candy strip. When theknives again are reciprocated toward each other, the pin' on the arm G5 moves outI of en @agement with the strip when the knives engage' the same, thereby .leaving the strip free to be moved forward with the Imovement of the knives. For the purpose of `holding/the candy ystrip in oper-V lative position a horizontal bar F5 is secured on a projection'from the standard `B4 and projects over the front end of the chute. A leafspring f'L is secured at one end of the said bar F5, and the other end extends into the end of said chutel at a point behind the rearmost limitlof the movement lof said knives. Said lfree end of said spring 4is turned over, as indicated in Figs. 6 and 9, and' presses lightly upon said candy strip, thereby acting to hold the endin position to be engaged by the knives.

Obviously from the construction so far described a space would be left on each side of the slide-bar adjacent to the caramel-carrying wheel, from which the cut caramel might fall from the chute when the knives are retracted.v

To prevent this, a depending plate f5 is provided on lthe inner edge of the bar F5 adjacent to the periphery of the carrying-wheel. Said .plate is offset from the bar F5 and is set slightly obliquely to the slide-harto permit the plate f3 on the slide-bar to pass between the same and the slide-bar at the forward limit of its movement, as indicated in Fig.'7. Said' yplate f3, asshown, is tapered on its front edge, thereby permitting both of said plates For the purpose of closing the space on the front side of the slide-'bar during said -'retraction an arm F 6 is pivoted on the standard B4 and extends upwardly and longitudinally of the-feedchute and is provided at its lower end', acl-- jacent to the pivot,'with ashoe f, which Arestsinfa depression in the surface of the' i slide-.bar when the same is at the rearwardlimit of its movement,but which as 'the slide-` bar moves forwardly causes said arm to risev upwardly, as indicated in dotted lines in-Fig. '6. At the free end of said arm is hinged a dependingplate f7, rounded at its lower end,

and adapted to close the space before the plate f2 when the slide-bar is retracted. of any desired kind is provided at the hinge for said plate f7 to permit the same to yieldingly-engage the caramel and holdthesame as shown in Figs. 6, 7, '8, and which acts to insure positive movement of Vsaid' arm correy ysponding with the movements of theshde-bar.

Said spr-ing, as shown,- is secured about a pivotalsleeveon'said arm,and the ends thereof engage, respectively, onl the arm and on the standard'B`. .It will thusbe seen that the A spring A spring f S, herein shown as a spiral sprlng, 1s provided for sald arm F,

'candy passes along a chute to the point where it is fed into the carryingwheel between practically continuous sidewalls. Each caramel Aafter it has thus been severed from the strip and fed to the point of delivery into the carrying-wheel E is removed from the slide-bar F and'out of the way of the following caramel vvb v a plunger comprising a head P, rigidly secured on the end of a rod p, which head is on the inner end of said rod and in position to .slide over the top of the slide-bar F of the feed-chute, as indicated in Figs. 7 8, and 9, and which plunger, actuated by suitable means unnecessary to be described for an understanding of our present invention, operates to force the caramels one at a time into suitably-disposed pockets e inthe intermittently-rotating carrying-wheel E when said pockets are moved to and held in the requisite register, after which the wrapping and other operations are performed by mechanisms which have no part in our present application.

Some of the drawings, notably Figs. l and 2, show not only the devices hereinbefore specically described as constituting our present invention, but also, for better understanding of the purpose of our invention, other instrumentalities and mechanisms usually comprised in an organized caramel cutting and wrapping machine, such as our aforesaid feeding and cutting devices are adapted to subserve. As will be appreciated by those skilled in the art, such machine comprises, as suggested by those parts of the drawings not hereinbefore specifically described, means for automatically feeding at the proper moment a requisite portion of the wrapper between the caramel and .the pocket e', into which the caramel, together v with such wrapper, is forced by the head P of the plunger above described, means for intermittently rotating the carrying-wheel E, -means for making the side and end folds of the Wrapper, and means for ejecting from the wheel the completely-wrapped caramel; but it will be understood that our present invention is not limited to be used in any one particular style of organized machine adapted to perform the said wrapping' operations, that detailed descriptions of the mechanisms for performing the said operations are not essential to a complete understanding of the operation and function of our present invention, -and that we have therefore presented in ou'r said drawings suggestions merely of one type of said mechanisms without further describing them, since no part thereof is included in our herein-described inventions or covered by the claims made by us in our present application for Letters Patent. p
